B) 3 chips. 2 x ROM/RAM chips and 1 (larger) Processor. There is 8K of ROM and 48 RAM registers in the 34C. Most likely 4K ROM and 16 RAM registers in each. I think there is some RAM also in the processor chip because the RAM map uses 48 registers. If the ROM chips don't support 4K then the extra must be also in the processor chip. cheers Tony |
